This paper will focus on the current growing threat of terrorist organizations as it applies to network security threats. There are many ways that common traditional cyber-attacks could be applied by these organizations that would result in devastating results. These include simple mass DDOS attacks on government or corporate systems harming the economy of a nation. There could also be intrusions into systems to gain sensitive information about national security or weapons plans and other advanced technology from government contractors. Lastly they could attack the accounts of companies and individuals or use ransom ware to gain access to near unlimited sources of funding. The paper will then detail both the effects of each of these potential attacks in the context of a terrorist attack and also the means that can be used to prevent them.
